An exception occurred while compiling Unidac using Aarch64

[zhougang2046]

Hello everyone,
 I encountered an exception while cross compiling the Unidac application for Aarch64 on Windows。
fpc & lazarus version:3.3.1 & 3.4
If using native controls, aarch64 can compile successfully, but when using a uniquery , compilation errors occur.
What other parameters need to be set for the compilation environment？
Thanks.

It is preferable to report compiler exceptions in the bugtracker no matter what the reason for the exception is.

Is your trunk version based on a recent version ? or is it older ?

I am not sure exactly what your target system is there ?

OS = Linux
Widget = Win32

Are you sure you need the trunk version of FPC ?  The fixes version is very stable and trunk varies day by day.  Unless there is a specific feature in trunk you need you might be better off using fixes.

@dbannon:
Perhaps my interpretation is wrong but from what i gathered TS is developing on windows and trying to cross-compile (to aarch).

My interpretation, too.
Would have expected a "Build-Mode Linux" or something, specifying THERE the correct LCL-Widgetset (GtkX, QTx)

Can you try 2 different experiments?

1. Turn off optimization when building your project (Compilation and Linking -> Optimization level to 0)
2. Disable Debug (Debugging -> Remove all checkmarks here)

Yes, its not clear but if you look at the image posted above the OP has TargetOS=Linux and widgetset=win32. That does not, to me, make a lot of sense. (but when I cross compile, I do it from the command line so don't see what Lazarus displays...)

And my other comment still seems relevant, does the same problem show in FPC-Fixes ? Using trunk does confuse the issue, are we looking a problem in the project or a (temporary) problem in the compiler ?

Thank you all！
I have found a solution, the website is https://www.cnblogs.com/qiufeng2014/p/18001664
After modifying according to this plan, the compilation worked properly.
